AWIMAL REPRODUCTIONS. 429 
from the third than ufual, fig. 11. Between 
them is a middle finger ftill very fmall, but evi- 
dently a new one, m. From the fame caufe, the 
fecond toe is alfo farther from the third than it 
. fhould be. Between them is feen the new toe, 7, 
which is to replace that which was loft. 
The wound on the metatarfus was now fo well 
healed, that no marks of it remained. Thefe 
immenfe wounds being healed by a kind of in- 
grafting, which effects the union of the parts, is 
no inconfiderable corroboration of a theory which 
I have fuggefted on the formation of certain mon- 
fters, that feem to originate from the accidental 
union of two organic wholes. Nor is the fuper- 
numerary finger, which I was able to give the 
newt, lefs favourable to it, 
EXPERIMENT VI.—We mutt not conclude, 
from the experiments in this and the preceding 
memoir, that, in confequence of longitudinal di- 
vifion, a new finger will always arife in the mid. 
dle of the member, and one, in this manner, 
have it in his power to produce a fifth finger on 
hands, and a fixth toe on feet, at pleafure: Ex. 
perience has taught me, that cleaving the mem- 
bers afunder is not uniformly followed by an ad- 
ditional reproduction. Many circumftanees, which 
we are yet unable to afcertain, may deeply influ-
